Abstract：
UNASSIGNED: In March 2019, students at Lempu Secondary School in Kweneng District, Botswana displayed symptoms including headache, abnormal leg movements and difficulty walking. Within days, 133 students were admitted to Scottish Livingstone Hospital where mass psychogenic illness (MPI) was diagnosed.
UNASSIGNED: To identify predictors of this illness.
UNASSIGNED: Kweneng West District, Botswana.
UNASSIGNED: This was a case control study using interviewer-administered questionnaires. Cases were students who displayed MPI symptoms from the 2nd of March to the time of the interviews or who were admitted with MPI diagnosis. Analysis was restricted to female students. Logistic regression was used to generate odds ratios. A p value of < 0.05 was considered to demonstrate significant association between variables.
UNASSIGNED: Interviews were conducted with 142 cases and 202 controls. The median age was 15 years. Most of the cases (95.8%) were boarding girls. Residence in school campus (AOR 13.2), history of evaluation by psychologist and/or social worker (AOR 2.6), history of traumatic events (AOR 1.8), contact with sick peers (AOR 2.3) and contact with spiritual healer (AOR 2.0) were independent predictors of MPI. Additionally, perception of adequate security in the dormitories (AOR 0.3) and perception of poor lighting (AOR 6.8) were significant predictors of MPI amongst boarding girls.
UNASSIGNED: The outbreak in Lempu Community Junior Secondary School (CJSS) was typical of mass psychogenic illness affecting mainly boarding girls and was associated with psychological and environmental risk factors. Changing the boarding environment and continuous psychological support are key to preventing future outbreaks. Interventions should also target the identified risk factors.

摘要：
■2019年3月，Kweneng区Lempu中学的学生，博茨瓦纳表现出包括头痛在内的症状，腿部运动异常和行走困难。几天之内,133名学生被送往苏格兰利文斯通医院，在那里诊断出大规模的心因性疾病（MPI）。
■确定这种疾病的预测因子。
■克文能西区，博茨瓦纳。
■这是一项病例对照研究，使用采访者管理的问卷。病例为从3月2日到访谈时表现出MPI症状的学生或因MPI诊断入院的学生。分析仅限于女学生。使用Logistic回归产生比值比。<0.05的p值被认为表明变量之间的显著关联。
■对142例病例和202例对照进行了访谈。中位年龄为15岁。大多数病例（95.8％）是寄宿女孩。居住在学校校园（AOR13.2），心理学家和/或社会工作者的评估史（AOR2.6），创伤事件史（AOR1.8），与患病同伴接触(AOR2.3)和与精神治疗师接触(AOR2.0)是MPI的独立预测因子.此外,宿舍中足够安全的感觉（AOR0.3）和照明不良的感觉（AOR6.8）是寄宿女孩MPI的重要预测因素。
■Lempu社区初中（CJSS）的爆发是典型的大规模心理疾病，主要影响寄宿女孩，并与心理和环境危险因素有关。改变寄宿环境和持续的心理支持是预防未来疫情爆发的关键。干预措施还应针对已识别的风险因素。
